Dynamics – CIE AS Level Physics 9702

understand that mass is the property of a body that resists change in motion

recall the relationship F = ma and solve problems using it, appreciating that acceleration and resultant force are always in the same direction

define and use linear momentum as the product of mass and velocity

define and use force as rate of change of momentum

state and apply each of Newton’s laws of motion

Non-uniform motion

describe and use the concept of weight as the effect of a gravitational field on a mass and recall that the weight of a body is equal to the product of its mass and the acceleration of free fall

describe qualitatively the motion of bodies falling in a uniform gravitational field with air resistance

Linear momentum and its conservation

state the principle of conservation of momentum

apply the principle of conservation of momentum to solve simple problems, including elastic and inelastic interactions between bodies in both one and two dimensions (knowledge of the concept of coefficient of restitution is not required)

recognise that, for a perfectly elastic collision, the relative speed of approach is equal to the relative speed of separation

understand that, while momentum of a system is always conserved in interactions between bodies, some change in kinetic energy may take place
